Building on an existing strength, the Tenth Edition contains expanded coverage of cultural influences on development, including increased coverage of ethnic gloss and individual uniqueness; and new coverage of the Attachment Q-Set, a new measure that offers better cross-cultural applications than older measures of attachment such as the Strange Situation. The photos and illustrations also show an ever greater commitment to depicting cultural diversity.

Increased coverage of historical influences on development begins in Chapter 1, which introduces the concept of historical generations, expands the treatment of the history of the study of human development, and updates Elder's work on studying the life course. Discussions in other parts of the book place in a historical context such topics as infant feeding, the comprehensive high school, and treatment of the dead and dying.

The research in the Tenth Edition has been thoroughly updated, including new research on adolescent brain development, and findings of the Changing Lives of Older Couples Study, including grief patterns after the death of a spouse. The coverage of adult development begins with extensive discussions of the newly defined life stage of emerging adulthood.
